AppIcaton filed January 7, 1909. Serial No. 471,087.

.To all whom it may concern.'

Be it known that l, HENRY B. HELM, a citizen of the United States, and aresident et' the borough of Manhattan, city and State of New York, haveinvented certain new and useful Improvements in Nozzles, of which thefollowing is a full and complete disclosure.

he object of my invention is to produce a nozzle, or nozzle tip,particularly intended lor use with tire hose for extinguishing fires,and so arranged that not only may different sizes et streams be thrown.from a single nozzle, but also a spray may be produced to cover largeareas oi the combustible matter in the immediate vicinity.

A further object of my invention is to providc a nozzle which will throwa backwardljT direct series of jets or spray, so that said nozzle may beused as a distributerH for throwing water over the entire interiorsurface of an inclosed space, or a room, when said nozzle is insertedthrough an opening in one wall thereof.

Other advantages oi my improved nozzle will be apparent from thefollowing description, and will be particularly pointed out in theaccompanying claims:

For a detailed description of one form oi my invention, which l atpresent deem prei"- erable, reference may be had to the followingspecification and to the acconlpanying drawing forming a part thereof,in which- Figure 1 is a longitudinal sectional view oi my improvednozzle; Fig. 2 is a side elevation thereof; Fig. 3 is a transversesectional view taken substantially on the line AA oic Fig. l, Fig. l isa longitudinal sectional view of several different iorms ol tips shownassembled, and which may be used to produce diilierent sizes andcharacter of streams from the main outlet oi the nozzle. Fig. 5 is aplan view of the perforated tip which may also be used to throw a singlesmall stream, when arranged as shown in Fig. 4.

Referring to the drawings, 1 indicates a reducer section or bushingwhich is screwthreaded so as to fit within my improved tip, and whichmay be varied in size at its outer end so as to accommodate diilerentsizes and makes of nozzles now on the market. rihis reducer or coupling1 screws into the main casing 2, which is preferably composed ol twoscrew-threaded parts 3 and 4L united by an interiorly screw-threadedunion or ring 5. Vithin the ring 5, and so placed as to beheld inposition by the adjacent ends oi the sections 3 and 4 of the casing, isa spider 6, prelerab y made of phosphor bronze, or some similar toughintrangible in aterial.

The iiange 7, uniting the inner ends of the spider arms 6, is rigidlyfastened to a screwthreaded tube 8 which forms the outlet proper lor thenozzle or tip when the largest size stream is used. The screw-threadedtube S carries a conical or cup-shaped part 9, having a conical suri'ace10, which cooperates with the end 11 ol the casing 2 to i'orm an annularopening through which water may be forced in the form o'll a spray. Theconical section 9 is provided with two arms secured adjacent its outerends, and diametrically opposite each other as indicated at 12. Thesearms extend parallel with the axis o1 the tip or nozzle, andv enter ears1.3 carried by the ring 14 rotatably held in position on the casing 2 bymeans of t're coupling ring 5.

l he lower end of the section oi' the casing 2 is provided withscrew-threads which connect it with a milled ring 1.5, so that when saidring is turned, the same will be moved longitudinally in relation to theaxis ol' the tip or nozzle. Section 4 oi the tip is provided with aseries oi inclined holes er openings 16 which extend toward and awayAl'rom the outer end oi' the tip, and these openings 16 are adapted tobe covered by the ring 15 when at the upper limit oi' its motion onseetion 4 ol the casing. A washer or packing ring 17 may be insertedbetween the end ol the coupling ring 5 and the ring 15 to further aid insecuring a water-tight joint between said parts, and prevent 'waterissuing through the opening 16 when the same is not in use. The bushingor reducer l carries a pin 18 which limits the motion ol the ring 15 andprevents it from becoming` disengaged. lrom the section 11.

The numeral 19 indicates a reducing tip which has a central tubularinterior-ly tapered portion 20 adapted to lit within the tube 8, and itsupper end is provided with a tubular ilange 2 l which is interiorlythreaded and adapted to engage the screw-threads on the exterior o'llthe tube 8. rThe outer end 22 of this tip is also screw-threaded inorder that a still l'urther reduction in the size-o1l the stream may besecured by the use of the parts shown in section in Fig. Ll. These partsconsist oi an interiorly screw-threaded cup-shaped portion 23 having aninterior-ly screw-threaded nipple 24. The latter receives thescrew-threaded tubular projection 25 oi' the perforated tip 26. Theopening through the tip 26 is preferably 3/16ths of an inch in diameter,to provide a very small stream, while the opening in the tapering tube2O is ol' an inch in diameter, in order to provide a stream of mediumvolume, the internal diameter of the tube 8 being preierably linches indiameter, which is the standard size used in 'fire nozzles. 1t will benoticed that the tip 26 is also cup-shaped and provided with a number ofopenings 27, the interior ol' the cup-shaped portion beingscrew-threaded and of such size as to screw over the end ol' the tube 8,should it be desired to use it in that position. W hen in the latterposition on the end oi' the tube 8, the periorations 27, together withthe central opening, will form a spray consisting oi a series of smallstreams which will distribute the Water over a considerable surface, andwith great iorce.

In the normal operation ol' my improved nozzle, the tip of the ring 14is turned so that the conical part 9 contacts with the end of section 3of the casing 2 thereb reventinfr. o 7 b any spray action. W hen it isdesired to use this protective or distributing spray, the ring 111 isgiven a su'l'licient number oi' turns to produce the desired volume ofspray, which issues in the form oi an even, practically unbrolenhollowcone oi' water. Should the interior oil a room or othercompartment be filled with flame or smoke, so as to prevent the entryo'f firemen, the entire nozzle may be inserted in a hole in the wall ofsuch apartment, and the ring 15 screwed to such a position, that thebacliwardly directed openings, 16 are uncovered. The ets issuing fromthese openings, together with the conical spray from the outer end ofthe tip, constitute a very effective and el'licient distributer whichwill throw the water over the entire surface of the room or apartment inwhich the nozzle is inserted. The use and application oi' the smallattachments i'or the end oi the tube 8 will be obvious to those familiarwith the use of such devices in eX- tinguishing fires.

Having thus described one form of my invention, l do not wish to beunderstood as being limited to the exact details of form and partsherein set forth, for various changes may be made by those skilled inthe art without departing from the spirit and scope of my invention.

What l claim and desire to protect by Letters Patent is:

1. 'A nozzle, comprising a casing, a screwthreaded tube locatedinteriorly thereof, a screw-threaded part carried by said tube andcoperating with the end of said casing to form a spray opening, and armsconnected with said screw-threaded part and extending rearwardly overthe exterior of said casing,
